[klibc/kinit in kernel]
I'd like to eventually move swsusp out of kernel, and klibc means I
may be able to do that without affecting users. Being in kinit is good
enough, because I can actually share single source between kinit
version and suspend.sf.net version.
Heh. Take a look at anyone who's using real initramfs for their boot
process. Not initrd, not kernel-without-any-preboot-fs, but real
initramfs. For them, if kinit/klibc will be in kernel, nothing changes,
because their initramfs *replaces* in-kernel code and future supplied-
with-kernel-klibc-based-kinit. So if you'll move swsusp into kinit,
it WILL break setups for those users!.. ;)
There are two ways to deal with this.
Either the kernel can unconditionally invoke /kinit, which then would
invoke the users /init if present, or the swsusp can be a separate
initramfs binary which the user's initramfs gets to invoke (the second
is arguably neater, but requires minor changes to the users initramfs.)
Either way, it's a trivial problem to solve.
